46 Claims.

The present invention relates to row-crop harvesting implements and is more particularly concerned with bean harvesters of the type adapted to be mounted on a tractor. The principal object of our invention is the provision of a new and improved bean harvester which is flexible in operation and is adapted for all crop and soil conditions.

Another object of the present invention is to provide an improved harvesting blade and supporting standard which are designed to increase the efliciency and versatility of the harvester as a whole.

A further object is to provide a bean harvester in which the harvesting blades and supporting standards are laterally adjustable to accommodate a wide variety of row spacings.

Another object is to provide an improved vine divider which is adjustable both vertically and laterally.

Still another object is the provision of an improved roller vine turner for opening a path between the tangled rows of vines without tearing plants out of the ground. A related object is the provision of improved bearing support means for the roller whereby the angle of the latter to the line of advance of the implement can be increased or decreased to meet crop conditions.

Another object of the present invention is to provide improved lifting connections between the tractor power lift and the implement tool holding means embodying both fine and coarse depth gauging means for controlling the working depth of the tools.

Referring now to the drawings, and more particularly to Figures 1-10, inclusive, reference numeral It indicates a tractor having a structural frame I i carried on a pair of rear driving wheels i2 and a forward dirigible truck l3. The implement attachment comprises a supporting frame which is similar to the cultivator attachment frame shown and described in Patent No. 2,150,665, granted March 14, 1939, to Miles H. Tuft, and reference is directed to the said patent for details of construction. Briefly, the supporting frame consists of a pair of transverse beams M which are suitably fixed to the tractor frame II and extend laterally outwardly from each side thereof. Preferably, although not necessarily, the beams M are in the form of heavy tubular members, each of which is welded at its inner end to an upwardly extending bracket I5, and the latter is bolted to the tractor frame H. A pair of spaced supporting plates iii are welded to each of the beams I4 and journaled in each of said plates are two vertically spaced, rearwardly extending, bail members 20, 2!. The

rear ends of bail members 20, 2| are journaled in plates 22 which are fixed, as by welding, to a transverse tool bar 23, preferably of square cross section. Clamped to the tool bar 23 at spaced intervals are the various tools which will be described in more detail presently, and bracing the supportingbeams I4 against the Weight of the tools are two diagonal bracing rods 24 which are fixed by bolts to the outer plate is and eX- tend upwardly and inwardly to a bracket collar 21 clamped on the upper portion of the tractor steering post 33. The rearward thrust on the beams it due to the reaction of the tools in the soil, is taken up by a pair of bracing rods 25 which are likewise fixed to the outer plate l3 by bolts 25 and extend forwardly and inwardly to a suitable bracket member 25 (Figure 12) carried on the lower portion of the steering post 33.

The tools carried on the tool bars 23 consist of two pairs of left and right blades. 3|, two pairs of vine dividers 32, and two outer roller vine turners 33. The blades 3| are arranged in pairs on either side of the tractor and-in the :present embodiment each pair convergesforwardly with their cutting edges 3] facing outwardly as shown in Figure 1. Each of the blades is carried by a tool standard or beam and is fastened to the underside of a foot 34 provided at the lower end thereof by .two countersunk bolts 36., 37 which are passed through suitably chamfered holes in the blade and aligned holes 36' 31' in the foot 34 and are secured by nuts on the threaded ends thereof. The nut on the forward bolt 36 ts down into a recess 4| provided in. the font 34, giving the latter a smooth, uninterrupted surfaceover which vines and. trash may pass freely without catching. The rearward nut 4|) is likewise recessed below the surface .of the foot 3 and rests upon a depressedshelf 4.2. Under certain conditions where the vines are extremely tough or the ground hard, it may bedesirable decrease the angle of the blade 3| to the line of travel of the tractor, and to thi end a bolt hole 43 has been provided in the foot 34- adjacent bolt hole 37 and spaced from hole 36' a distance equal'to the distance between holes 36, 3'5. To change the angle of the blade, the bolt 3T is withdrawn from hole3'l, the blade 3| turned about bolt 33 as a pivot to align the hole in the blade with bolt hole 43, and the bolt :33 is passed through the aligned holes and tightened As will be noted in Figure 5, the blade 3| is disposed at a slight angle to the surfac of the ground with the sharpened edge 3i inclined downwardly. This provides clearance and prevents the underside .of the blade from-dragging or scraping on the ground, reducing friction and thereby decreasing the draft. The standard 35 curves upwardly and rearwardly fromthe foot 34 and is provided with a lug 47 formed integrally on the back side thereof having holes 44 adapted to receive and hold windrow rods for deflecting the cut vines to either side. standard curves forwardly again and is bent latorally to form an offset portion 45, the purpose of which will become evident shortly. Th end of the standard is provided with a forwardly facing V-shaped socket 43 adapted to fit up-against the tool bar and a correspondingly V-shaped captfi secured to. the standard by bolts 5|, best shown in Figure. 4.. .By virtueof the square cross section of the tool .bar23 and the form of the socket 455 and th clamping part 5%, when the bolts 5| are tightened, the standard is rigidly secured to the tool bar against displacement laterally or otherwise. The latter member is of uni form cross section throughoutits length so that any desired spacing of the blades-may be secured by merely loosening. the bolts 5| and shifting thetool standards 35 along thebar 23 to the desired position. Likewise, the right and left hand blades may be rearranged .on the tool bar to cut ine upper end of the wardly, as shown in Figure 11, by removing the caps and reversing the position of the standards along the tool bar, or the two outer blades and standards can be removed to convert the implement into a two-row harvester.

The dividers 32 are preferably formed of pipe and are adapted to be clamped to the tool bar 23 adjacent the blade standards 35 and extend downwardly and forwardly therefrom ahead of the blades 3| to separate the rows of intertwined vines, each divider terminating in a flattened and pointed toe 52 having a transverse hole 53 formed therein. Formed integrally along the length of the back side of each divider 32 is a rearwardly projecting lug 54 having a plurality of holes 55 which are adapted to receive and hold windrow rods 55. Thelatter consist of long rods having the front ends thereof bent laterally at an angle to pass through suitable apertures in a short bar '59 to which th rods are welded. The apertures in the bar 59 are spaced apart to coincide with the holes 55 in the lug 54, and the projecting ends of the rods are passed through holes 55 and threaded to receive nuts 60 on the opposite. side of the lug. By tightening the nuts 60 against the lug 54, the windrow rods '56 are rigidly secured to the divider 32, extending rearwardly therefrom at an angle corresponding to the angle of the associated blade 3| to deflect the cut vines to either side and deposit them in Windrows suitable for gathering up with'a rake or like implement. Where it is not necessary to use the dividers 32, as when the vines are lying close to the ground and are not unduly tangled, the windrow rods 56 may be bolted to the lug 4-1 on the back of the blade standards 35, and the laterally bent front end portions of the rods passed through holes 44. With this arrangement the blade standard 35 acts in the capacity of the divider 32 to separate the tangled rows of vines. When the rows of vines are extremely tangled and the divider 32 tends to pull plants out by the roots, improved results are often obtained by setting the blades substantially as arranged in Figure 1, raising the pipe dividers on the tool bar 23, and bringing each pair of dividers together tosupport a rolling colter therebetween in the holes 53.

The dividers 32 are mounted on the tool bar 23 by clamping means best shown in Figures 8 and 9 and comprising a block 6| having a V- shaped notch 62 formed in one side thereof and a substantially U-shaped channel 63 formed in the opposite side thereof and extending at right angles to the notch 62. The block 6| is placed between the tool bar 23 and the divider 32 with the V-shaped notch '62 fitted against one corner of the square tool bar and the divider seated in the channel 83. A pair of eye bolts 64 embrace the divider 32 at either end of the block 6| and the shanks of said eye bolts are passed through suitable apertures in the ends of a clamping member 55 and are secured by clamping nuts 66, as best shown in Figure 8. To adjust the divider 32 laterally, the nuts 66 are loosened and the block GI and associated clamping elements are shifted along the tool bar 23 to the desired position. Likewise, to raise or lower the divider 32 relative to the ground, the nuts 66 are loosened and the divider is moved up or down through the eyes of eye bolts 64.

The outer two roller vine tumors 33 are also mounted on the tool bar 23 and are disposed midway between each pair of blades 3| extendmg appreciably ahead'thereof to open a path through high standing and excessively tangled vines, thus serving as means for guiding the vines to the blades 3I Each of the roller vine turners consists of a U-shaped rear bracket I having a plate H welded to its upper edge and V-notches I2 in its lower edge adapted to receive the tool bar 23 therein, as best shown in Figure 10. Two U-bolts I3 embrace the tool bar 23 and pass through suitable perforations in the plate II, being secured to the latter by nuts I4 on the threaded ends of the bolts. The legs of the U-shaped bracket extend forwardly and downwardly and are pivotally connected by a transverse bolt to a pusher frame I6 comprising a pair of laterally spaced, forwardly reaching parallel bars 80. The front ends of the bars 80 are pivotally connected by a transverse bolt 8| to lugs 82 provided on the roller support frame 03, and guide members 84 are welded to each of the bars 80 intermediate of the ends thereof, projecting upwardly on eitherside of said roller support frame. The latter consists of a bar bent into the general shape of an L having a horizontal runner portion 35 and a vertical portion 86, and is braced by a diagonal strut 90. The front end of the horizontal runner portion 85 is bent upwardly and apertured, as at 9|, to receive the shank 92 of a ball bearing member 93, said shank having a flange 94 adapted to bear against the top side of the bar 85 and threads on the end portion projecting below the bar for receiving a clamping nut 95 thereon. The upper end of the shank 92 is provided with a ball 95 which is received within a socket member 91 mounted on the lower end of the tapered roller I00. The upper end of the vertical portion 06 of the frame bar is bent forwardly to provide a curved portion IOI arcu ate about the center of the ball 56 and having a plurality of holes I02. The upper end of the roller N is journaled on a ball bearing member I03 mounted on the arcuate portion If" and comprising a shank I04 having a ball m5 at one end thereof and a flange I05. The ball I65 is disposed within a socket IIO fixed to the upper end of the roller I50, and the opposite end of the shank I04 is received within a suitable aperture in a plate III with the flange I95 bearing against the plate and preferably welded thereto. The plate III is also provided with two holes IIE spaced to coincide with holes H32, and bolts II3 are passed through aligned hbles IE2, H2 and secured by nuts I54 on the threaded ends thereof. The angle of the roller IdI) relative to the line of advance of the tractor can be increased or decreased to meet varying harvesting conditions by merely removing the bolts IE3 and moving the plate III up or down along the arcuate portion IEI to align the holes H2 with another pair of holes I02. The bolts H3 are then replaced in the aligned holes and the nuts II4 tightened, Best results are obtained by setting the roller so that the vines travel up the roller as high as possible before being separated, but without any vines pulling over the top of the roller. The correct angle varies with different heights and conditions of vines and with the speed of the tractor and can be ascertained only by experiment. In order that the roller I00 may rotate freely on the bearing balls 36, I05 at all times, the frame 83 is made somewhat flexible and the strut 00 is connected thereto at one end by an adjustable connection comprising a lug H5 provided on the vertical frame portion 06 and having a longitudinal slot II5 formed therein. A connecting bolt I20 is passed through the slot H6 and a suitable bolt hole in the strut 90, and by shifting the bolt I20 in the slot I I6, the upper and lower bearings 93, I03 are separated or drawn together, as the case may be, to provide more or less clearance between the bearing balls and their respective sockets. The lower bearing 93 is shielded against trash and low vines lying close to the ground by a boot I2I which is fixed to the front end of the frame member in any suitable manner and extends up over the lower end of the roller.

Mounted on the front end of the tractor I0 and extending ahead thereof to open a path through the tangled vines for the dirigible truck I3, is an inner or center roller vine turner or plant guiding means I 22 which is identical to the outer vine turners or plant guiding means 33 but is connected to the tractor by means which will now be described. A mounting bracket I23 is secured to the steering post 30 by U-bolts I24 (Figure 2), and fixed to the bracket I23 by a clamping member I25 and bolts I26 is a downwardly and forwardly extending beam I30, preferably of square or rectangular cross section. The beam I30 is braced by a pair of tubular bracing members I3I which are suitably fixed to the tractor frame II on either side of the steering post 30 and curve downwardly and forwardly therefrom, being secured to the beam I30 by a clamping member I32 and bolts I33. A forwardly extending pushing member I34 is pivotally connected by a transverse bolt I35 to the lower end of the beam I30 and is connected by a pivot bolt I36 to the frame of the center roller vine turner.

The tools are raised and lowered between operative and inoperative positions by the tractor power lift, indicated generally by the reference numeral I40, and the depth at which the tools operate, as well as the lifting of the tools, is controlled by two similar mechanisms disposed on opposite sides of the tractor. For a detailed description of the construction and operation of the power lift, reference may be had to Patent No. 2,107,760 granted to McCormick, Worthington, and Stewart on February 8, 1938. An actu-- ating rock shaft I 4| projects laterally from the ends of a transversely disposed hOllsing I42 mounted on the rear end of the tractor Iii, and clamped to each end of the rock shaft MI is a forked lifting arm I43. A collar I44 is rotatably supported between the ends of the forked lifting arm I43 on trunnions I45, and slidably received within said collar isa push rod I46 which extends forwardly to a bifurcated arm I50 fixed tothe transverse portion 20' of the upper bail member 20. A sleeve I5I is rotatably supported between the ends of the bifurcated arm I50 on trunnions I52 and is adapted to receive the front end of the push rod I45, allowing the latter to turn freely within the sleeve I 5| while restraining axial movement relative thereto.

Each lifting mechanism preferably comprises a pipe I4'I disposed ahead of the collar I44 and embracing the rod I46 in sliding engagement therewith. A set collar I48 is adjustably fixed to the rod I46 and spaced ahead of the front end of the pipe I41 a short distance when the tools are lowered in operative position to provide for a limited amount of lost motion in the lifting connections. In the operation of the power lift I40, the lifting arm I43 is rocked, causing the pipe I41 to engage the set collar 48, thereby effecting" a forward movement of the rod. I45. Inasmuch as the rod I46 is connected to the upper endof the arm I50; and the latter is connected to the bail member 20, a forward movement of the rod I46 causes a clockwise rotation of bail member 20, resulting in the lifting of the tool bar 23 and associated tools out of operating position.

The depth of operation of the tools mounted on the tool bar 23 is controlled by means of a stop device comprising a sleeve I 53 which is threaded upon a suitably threaded portion of the rod I45. The outer periphery of sleeve I53 is of rectangular cross-section and is provided with a flange stop I54 at the front end thereof. A holding member I55 having a similar rectangular "aperture adapted to cooperate with the periphery of the sleeve I53 is-slidably but nonrotatably engaged with said sleeve and is adjustably fixed to the front end of a rod I55. The rear end of rod I55 is pivotally connected at I60 to a depth gauging hand lever II which is connected by apivot bolt I52 to a bracket I63 mounted on the tractor rear axle housing II. The hand lever IEI is locked in position by the usual latch mechanism I54 engaging a notched sector IE5 fixed to the bracket I53, thereby locking the holding member I55 against longitudinal displacement. As the tool bar 23 moves downwardly into operative position, the lever arm I 50 rocks counter-clockwise, as viewed in Figure moving the push rod I45 and sleeve I53 rearwardly. The flange stop I54 abuts against the front end of the holding member I55, limiting further rearward movement of the push rod I46, and the depth of operation of the harvesting blades 3I is thus determined by the longitudinal position of the holding member I55 as regulated by the lever I6I.

Finer depth adjustment may be secured by turning a hand wheel I66 which is fixed to the rear end of each of the push rods I 46, rotating the latter to change its position with respect to the sleeve I53 in which its forward end is threaded. When rod I45 is rotated, the sleeve I53 is prevented from turning with it by the holding member I55.

The lost motion provided by the gap between the front end of the pipe I41 and set collar I48 enables the lifting mechanism to raise the tools on the tool bar 23 to substantially the same elevated position each time regardless of the depth setting as adjusted by the sleeve I53 and holding member I55. Under certain conditions it is desirable to utilize the full effective stroke of the lifting arms I43 in raising the roller vine turners, however, and to this end a separate set of lifting connections have been provided which are operatively connected with the ipe I41. The pipe I41 is also connected to the lifting arm I43 by means of a short link or bar I10 which is fixed, as by welding, to the rear end of the pipe and is journaled on the inner trunnion I45, so that the pipe I41 moves with the arm I43 through the full stroke of the latter. Provided on each of the pipes I41 and extending upwardly therefrom is a lug Ill, and journaled in the lug on the right hand pipe I51 is the outwardly turned rear end of a fore and aft extending push rod I12. The front end of push rod I12 is pivoted at I13 (Figure 1) to an arm I14 which is fixed to a rock shaft 515 and curves downwardly and rearwardly therefrom. Rock shaft I15 is supported in suitable bearing means carried on the. mount ing bracket I23, and is fixed to a forwardly extending lifting arm I16. A lifting chain I is fastened to the end of lifting arm I16 by a connecting bolt HM and is secured to the center roller vine turner frame at I32. A loop of chain I83 is passed around the beam. I30 and connected to chain I80 adjacent the lower end thereof to act as a snubber for the center roller vine turner when the latter passes over a depression in the ground and tends to nose down.

When the power lift Mil is actuated, the pipe I41 and push rod IE2 are caused to move forwardly, rocking the rock shaft I15 in a counterclockwise direction and lifting the center vine turner on lifting arm I16. The chain I80, being a flexible element, is in the nature of lost-motion means, whereby'when the tools 3| and the vine turner or plant guiding means I22 are in their lowered position, the latter is capable of upward movement independent of the tools 3|.

A longitudinally disposed push rod I 34 is pivotally connected at its rear end to the lug l1I provided on the left hand pipe I41, and is pivoted at its front end to an arm I85 clamped to a transverse rock shaft I85. The latter is journaled in a pair of laterally spaced bearings I93 carried on a transversely disposed beam I9I which is fixed in any suitable manner to the bracket I23. A pair of spaced lifting arms I92 are clamped to the rock shaft I35 and extend downwardly therefrom, each of said arms lying substantially in the vertical plane of its respective outer vine turner 33. Fastened to the end of each of the arms i9? is a chain I93 which is also connected to the vine tulner frame and which serves as both lifting chain and snubber chain to prevent the vine tumors from nosing over. When the power lift is actuated, the pipe I41 and push rod I84 are moved forwardly, rocking the rock shaft I85 in a clockwise direction and lifting the two outer roller vine turners 33 on lifting arms I52. Since the chains I53 are also flexible elements, they form lost-motion means, whereby the outer vine turners or plant guiding means 33 may also move upward independent of the tools 5 I.

In certain types of power lifts such as the hydraulic lift I45! illustrated herein, the actuating rock shaft I4I is not returned from raised to lowered position by the positive application of power but depends, rather, on the weight of the implements to rock the shaft back to normal position. To facilitate the lowering of the tools to operative position, especially when using a minimum of operating units, a return spring I94 has been provided, one end of the spring being fastened to a link I55 pivoted at 553 to bracket Z00 fixed to the lifting arm I53 and the other end being anchored to a lug as: provided on the bracket member I53. The spring I54 urges the rock shaft IM to rotate in a counter-clockwise direction and speeds up the lowering of the tools to the ground. 4

Referring now to Figures 11 and .2, the embodiment illustrated therein is similar in most respects to the previously described embodiment with the exception of the roller vine turners which have been replaced with a single boot vine turner disposed ahead of the tractor dirigible truck I3. Like the vine tumors 33 described above, the single boot vine turner 252, described below, also serves to guide plants toward the blades 3 I.

This type of bean harvester operates as satisfactorily under certain crop conditions a the previously described embodiment and has the additional advantage of being cheaper to manufacture. It will be noted in Figur 11 that the arrangement of the blades 3| and standards 55 has been reversed on the tool bar and that the cutting edges 3| of each pair of blades face inwardly and converge rearwardly, with the windrow rods 56 forming two windrows between the rear tractor wheels. Another point of difference is that the two inner dividers have been dispensed with and the windrow rod 56 attached to the lugs 41 on the standards 35. In thi way the inner standards 35 can be clamped to the inner ends of the tool bars 23 and the blades 3! positioned beneath the tractor, by virtue of the offset 45 in the standard, to accommodate extremely close row spacings.

The boot vine turner or plant guiding means, indicated in its entirety by the reference numeral 202 comprises a supporting fram 283 fixed to the tractor, an arched fender 2M pivoted on the front end of the frame 293, and a lifting device operatively connected with one of the pipe members I41 for swinging the fender 2534 up to inoperative position.

The frame 253 consists of a transversely disposed bracket member 295 fixed to the lower.

portion of the steering post 30 in any suitable manner and having its ends bent forwardly to provide lugs 285. A pair of spaced side members 210 are connected to the lugs 296 by bolts 2H passed through any of several holes M2 in the ends of members 2E0, and extend forwardly an downwardly therefrom, being connected together at their front ends by a transverse rod 2|3. A pair of bracing struts 2M are bolted to the bracket collar 21 on the steering post 39 and extend downwardly and forwardly, being connected to their respective side members 2H5 by bolts 2l5 passed through any of several adjusting bolt holes in the struts and side members.

Journaled on the rod 253 substantially midway between the side members 210 is a supporting arm 2l6 which extends rearwardly and terminates in an arched portion 226 to which the fender 204 is fixed. The fender 2M is raised to inoperative position by means of a U-shaped member 22L the legs of which are journaled on the rod 2l3, and the transverse portion of which is adapted to engage and pick up the arm 2E6 when the member is rocked in a clockwise direction (Figure 12) A push rod 222 is pivoted at its rear end in the lug I'll provided on the right hand pipe I41, and extends forwardly therefrom, being pivotally connected at its front end to a lever arm 223 fixed on a transverse rock shaft 224 journaled in the side members 2IU. A second lever arm 225 is fixed to the rock shaft 224 and a link 228 is pivotally connected to its end. Th other end of the link 226 is connected to a lever arm 233 fixed to one leg of the U-shaped member 22!. Thus, when the power lift M0 is actuated, the pipe I41 and push rod 222 are moved forwardly, rotating the rock shaft 224 in a clockwise direction and causing the u shaped member 22! to rotate likewise, picking up the arm Zlt and fender 2M and swinging them backwardly and upwardly to inoperative position.

A spring MI is fastened at one end to a bracket member 232 fixed on the arm 296 and is hooked at the other end through an eye bolt 233 secured to the U-shaped member 221 to hold the fender 204 yieldingly down to its work. The spring 22%| and associated parts permit the fender 204 to move upwardly independently of the position of the blades 3|, thus in effect forming lost-motion means.
